For Frances Wynn, widow to the late Earl of Harleigh, life has a cosmopolitan flavor of late. No sooner has she sent her mother and daughter off on a shopping trip to Paris than she and her fiancé, George Hazleton, are socializing with visiting members of the Russian royal family. Yet amid this whirlwind, scandal also comes calling when Inspector Delaney turns up outside Frances’s house with a young French woman with a shocking claim: she is Mrs. George Hazelton.

As the future Mrs. George Hazelton, Frances assumes the woman is either lying or demented. “Mrs. Hazelton,” aka Irena, makes other outrageous statements. Among them, she insists that she is the illegitimate daughter of Russian royalty, that she has been abducted and held for ransom many times, and that someone is sending her threatening letters. When George arrives, he clarifies that he is certainly not married to Irena–though he can confirm her royal parentage.
